Title: Liquid-permeable film of thermoplastic resin
Inventor: DEIITERU ROOZE
IPC: A61F13/15
Filed: 1988-07-13
Abstract: PURPOSE: To make a film well permeable even to liquid having the viscosity extremely higher than the viscosity of water by increasing the section of openings toward the free edge of the projections on the film from the position of the film where the openings are narrowest. CONSTITUTION: The film placed on a perforated plate is pressed into the feed holes of a plate by a differential pressure and is then ruptured toward the inner side. The thickness of the plate 1 and the deformation properties of the film 3 are determined by forming air bubbles 6 of the diameter larger than the average diameter of the feed holes 2 before the rupture on the rear side of the feed holes 2 of the plate 1 under the effect of the differential pressure. The plate to be used is extremely thin with respect to the diameter of its feed holes and the characteristics of the material at the deformation temp. are such that the air bubbles of the diameter larger than the diameter of the feed holes of the plate are formed on the side of the plate by parting from the side where the thermoplastic film exists before the film is withdrawn within the feed holes and is ruptured.  The rupture shape required for the free edges of the projections or the irregular or wrinkled structure is thereby automatically attained.

Title: Resin spin welding member
Inventor: SHIBAYAMA TERUTSUGU
IPC: B29C65/06
Filed: 1986-07-23
Abstract: PURPOSE:To prevent excessive frictional heat from generating and consequently warpage and wrinkles from generating on the rear surface of a board by a method wherein through holes are provided on a flange part in a spin welding member having the flange part, which is to be welded to the resin board. CONSTITUTION:Through holes 13 are provided on a flange part 11 in a resin spin welding member having the flange part 11, a columnar part 10 and engaging projections 12 to be engaged with a rotary jig. Through the phenomena of 'heat transfer to rear surface' or of the generation of warpage, wrinkles and the like on the rear surface of a board 17 may occur due to excessive frictional heat when the resin board 17, onto which the flange part is welded, is thin, the provision of the through holes 13 on the flange part 11 prevents the above-mentioned phenomena of 'heat transfer to rear surface' from developing, because excess heat is effectively dissipated through the through holes and consequently does not be transmitted to the rear surface of the board 17. In addition, the molten resin 17a of the board 17 advances into the through hole 13, resulting strongly integrating both the board and the flange part with each other.
